Some interesting and relevant information released from the National Transportation Safety Board today:

Inward-facing video with audio captured the crew’s actions and their conversations. A forward-facing video with audio captured conditions in front of the locomotive as well as external sounds.

The crew was not observed to use any personal electronic devices during the timeframe reviewed.

About six seconds prior to the derailment, the engineer made a comment regarding an over speed condition.

The engineer’s actions were consistent with the application of the locomotive’s brakes just before the recording ended. It did not appear the engineer placed the brake handle in emergency-braking mode.

The recording ended as the locomotive was tilting and the crew was bracing for impact.

Two people were killed in a crash involving a freight train and an Amtrak passenger train early Sunday in South Carolina.

Amtrak Train 91 was traveling between New York and Miami with 147 people aboard when it collided with a CSX freight train in Cayce at about 2:35 a.m., derailing the lead engine and some passenger cars, Amtrak said in a statement.

The CSX train was stationary on the tracks, "awaiting a later movement," when the collision occurred, Gov. Henry McMaster said in a press conference Sunday morning.
